How to use CPD on ITK Code?

• Currently, CPD only support the following extensions for c++ files ".h", ".c", ".cpp", ".cxx", ".cc", ".C".

Short term solution

• So you first need to copy all the ITK sources and change the extension of all *.txx files to .cc
• Then first replace existing /path/to/pmd/bin/cpd.sh by this one

$ cd /path/to/pmd/bin $ ./cpd.sh /path/to/Insight/Code 500

Long term solution

• Modify CPPLanguage.java in order to make CPD work with txx file.
• Debug see http://sourceforge.net/projects/pmd/forums/forum/188192/topic/3778230
